BY M m Marvin Walker A I United States Patent AUXILIARY SUPPORT FORSHEET METAL SHEAR TABLE Marvin Walker, Macon, Ga.

Application November 2, 1955, Serial No. 544,449 4 Claims. (Cl. 311-17)commonly employed in association with metal cutting shears and the like,whereby to facilitate the handling of stacks of metal sheets and formoving and positioning the same With respect to the shear table and themetal shears.

A further object of the invention is to provide an auxiliary supporttable construction in accordance with the preceding object which shallbe of an extremely light weight character, may be compactly storedrelative to the sheet metals shear table, and may be easily appliedthereto or removed therefrom.

A further object of the invention is to provide an auxiliary tableconstruction for use with a sheet metal shear table in which a combinedmeans is provided for hinging the support table structure to the sheartable and for assisting in supporting the support structure from thesheet metal shear table. I

And a final important object of the invention to be specificallyenumerated herein, resides in the provision of an auxiliary supportstructure for a sheet metal shear table in which one or more auxiliarysupport tables shall be pivotally mounted upon and partially supportedby the sheet metal shear table with their tops disposed above that ofthe shear table whereby horizontal swinging movement may be imparted tothe support tables into positions either above or to one side of thesheet metal shear table.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

Figure 1 is a perspective view showing a preferred manner of applyingthe principles of this invention, the same illustrating the particularmanner in which a pair of auixiliary support tables may be detachablypivotally secured to and partially supported by a sheet metal shear ure1, alternative positions of the support tables being shown in full anddotted lines therein, and their relative swinging movement beingindicated by the arrows; and

Figure 4 is a fragmentary group perspective view showing the detachablepivotal connecting means of the support table and the shear table.

Referring first to Figure 1 it will be seen that the sheet metal sheartable indicated generally by the numeral 10 is of conventionalconstruction, the same including a flat top 12 which is supported by aplurality of legs 14 and is provided with brace members 16. Customarilythis table is conveniently associated with and positioned approximate tosheet metal shears and the like. In accordance with this invention, thetop 12 is provided with a plurality of apertures 18 which constitute apart of the pivotal connection of the auxiliary support tables eachindicated generally by the numerals 20, as set forth hereinafter.

Each support table has an open frame top, preferably right angular inshape, and composed of angle iron members 22 joined at their ends. Twoof the corners of the triangular tops are supported by legs 24 providedwith casters 26, while a third corner is pivotally connected to the topof the shear table 12.

The pivotal connection for this purpose is shown best in Figures 2 and 4and consists of a pin having a cylindrical upper portion 28 welded orotherwise secured to a pair of frame members at their joint, and isprovided with a depending diametrically reduced pin or cylindricalportion 30. The junction of the portions 28 and 30 provide an annularbearing surface 32. The pin 30 constitutes a hinge member which isdetachably received in a selected aperture 18 in the top 12 of the sheartable, while the annular surface 32 constitutes a bearing surface whichis adapted to rest upon the table top, as shown in Figure 2.

The legs 24 are of such length and the pivot pin is of such dimensionsthat the tops of the support tables are positioned at an elevationslightly above that of the top of the shear table, whereby each supporttable may be swung in a horizontal plane to cause its top to bepositioned either overlying or to one side of the shear table top.

As indicated best in Figure 3, it will be seen that by means of thecasters one or both of the auxiliary support tables may be swunghorizontally to various positions, as from the full line to the dottedline positions. Thus, a stack of metal sheets'to be cut by a shear canbe easily moved with respect to the sheet metal shear table, therebygreatly facilitating the handling of the sheets and reducing the extentof labor required.

It will be observed that the pivot means constitutes both a means forhingedly connecting the support tables to the shear table, and alsoconstitutes a part of the support means for the support table. Thedevice can be readily moved into a compact position as by swinging thesupport table tops over the shear table top, and the support tables canbe readily removed or disconnected from the shear table.

What is claimed as new is as follows:

1. An auxiliary support for a sheet metal shear table of the type havinga flat, unobstructed top together with supporting legs therefor, saidauxiliary support including a supporting framework constituting a topand a pair of legs supported by casters and secured thereto, a pinhaving a shank detachably seated in an opening in the shear table topadjacent and inwardly of a leg thereof, the top of said support tablehaving a socket remote from the legs of the support table, said supporttable having its top disposed higher than that of the shear table withsaid pivot pin engaged in said socket whereby said support table may beswung horizontally about said pivot pin to dispose its top in positionsoverlying and to one side of the shear table top.

2. In combination, a sheet metal shear table having a flat,non-circular, unobstructed top with supporting legs secured at thecorners thereof and a pair of support tables pivoted to said top forhorizontal swinging movement, each support table having a pair of castersupported lugs and a top carried thereby, each support table having itstop higher than that of the shear metal table, the top of the latterhaving openings therein adjacent and inwardly of its support legs, eachsupport table top having a pivot pin depending therefrom and receivablein one of said openings whereby each support table will be carried byits pivot pin and support legs and may be swung horizontally about itspivot pin to dispose its top to positions at one side of or overlyingthe top of the shear table.

3. The combination of claim 1 wherein the top of said support table is apolygonal shaped open frame, said pivot pin and said pair of supportlegs being each disposed at a corner thereof.

4. The combination of claim 1 wherein said pivot pin having adiametrically enlarged portion received in said socket and supportingthe support table top, an annular bearing shoulder at the junction ofthe shank and enlarged portion and engageable upon the shear table top.
